The detailed model was reproduced on a MATLAB situation for four cycles with each cycle at Cross-type convergence viable.  ...  The graph coloring technique was planned by including a boundary (mLan) to the underlying sign timing plan (iLan) to give the following theory signal timing plan.  ...  Graph Coloring Algorithms There are numerous heuristic consecutive procedures for coloring a graph. One of them is the Greedy Graph Coloring which was received in this paper.  ...

Cyclic Sparse Greedy Deconvolution

Khalid SABRI
2012 International Journal of Image Graphics and Signal Processing  
The purpose of this study is to introduce the concept of cyclic sparsity or cyclosparsity in deconvolution framework for signals that are jointly sparse and cyclostationary.  ...  Given the Impulse Response (IR), the aim is to retrieve the original object which has been distored by passage through a known linear and time-invariant system in presence of noise.  ...  Thus, ̃ is a matrix with particular structure i.e. the nonzero columns for each cycle are deduced by shifting the columns of the first cycle with a multiple of the cyclic period .  ...

1996 Proceedings of the twenty-eighth annual ACM symposium on Theory of computing - STOC '96  
Acknowledgements We thank Nabil Kahale, Tom Leighton, and Ken Sevcik for valuable discussions on queueing theory and routing.  ...  We also show that any greedy discipline is stable on the directed cycle for a smaller injection rate of single paths. (5) Let P be an arbitrary greedy queueing discipline, and G the directed cycle.  ...  Probabilistic analyses in which a Poisson or Bernoulli process generates packets bound for random destinations; the passage time through an edge is a constant as in packet routing (see [9] , for example  ...

Inference of multiple trajectories in single cell RNA-seq data from RNA velocity [article]

Ziqi Zhang, Xiuwei Zhang
2020 bioRxiv   pre-print
These methods are often restricted to certain trajectory structures like trees or cycles, and the directions of the trajectory can only be partly inferred when the root cell is provided.  ...  We present CellPaths, a single cell trajectory inference method that infers developmental trajectories by integrating RNA velocity information.  ...  We use mean first passage time 50 as the pseudotime for the random walk based method.  ...

field evaluates its path set for collision a single time before following the chosen path in entirety.  ...  A path-set-based planner navigates by repeatedly testing each of these robot-fixed paths for collision with obstacles. A heuristic function selects which of the surviving paths to follow next.  ...  A greedy planner naturally attempts to graze every obstacle (and follow narrow passages) where doing so minimizes the heuristic solution cost.  ...
